Green Bay Packers tight end Jermichael Finley went public Friday with his frustration over the $15,750 fine he received for what the NFL determined was an illegal crackback block in last weekend's win over the Baltimore Ravens.

"Thanks To @nfl For The Fine For Playing Football," Finley wrote on Twitter.

Finley wasn't penalized on the field for the block on Ravens linebacker Terrell Suggs, who didn't see the block coming near the line of scrimmage on a toss-right run play.

But the NFL determined the block was illegal under Rule 12, Section 2, Article 7 (a) (9), which protects any player in a "defenseless posture" from such blocks.

Finley told reporters in Green Bay he plans to appeal.

The NFL confirmed earlier in the week that Detroit Lions defensive tackle Ndamukong Suh was fined $31,500 for a hit on Cleveland Browns quarterback Brandon Weeden.
